In this paper, we discuss the operational convenience and safe driving when operating a human-machine interface (HMI) while driving on a virtual expressway. We previously conducted an experiment to evaluate a center-cluster panel switch and two prototypes of new HMI with a head-up display (HUD) and steering wheel switch (SWS) in which the participant followed a lead vehicle on an expressway by using a driving simulator (DS). We also conducted another experiment to evaluate these new HMIs when a driver operating an HMI encountered a sudden danger while driving. However, in these previous experiments, the number of switch pushes was not the same for each HMI. In this study, we compared the participants' switch operation performance, eye movement, and reaction to sudden danger in the new experimental condition, where the number of switch pushes is the same for each HMI, with those of the previous work.

An experimental method was required to evaluate both the operability and the influence on safety of in-vehicle devices used while driving. We proposed to measure the number of errors, operation time, glance time, and variations in steering angle and yaw angle through objective tests, as well as eliciting subjective evaluations by participants. We conducted an experiment in which, using a driving simulator to evaluate a center-cluster panel switch and a new human-machine interface (HMI) with a head-up display (HUD) and steering wheel switch (SWS), the participant follows a lead vehicle on an expressway. Results indicate that the experimental method is effective for comprehensively evaluating in-vehicle devices and identifying where improvements are needed. The merits of the new HMI are also discussed.

We conducted an experiment to evaluate the operational convenience and the influence on safe driving of a new human-machine interface (HMI) by using a driving simulator (DS). In this system a driver operates the new HMI and center-cluster panel switches while driving on an expressway and when encountering a sudden danger. Based on the results, we discuss the operational convenience and driving safety when operating an HMI while driving on a virtual expressway.

We conducted experiments to collect data on vehicle speed to investigate the movement of a car without the right of way passing through an intersection. Movement was measured at each moment by the distance between the stop line and the car. This was accomplished by using video cameras and a laser displacement meter. We analyzed drivers' common driving behavior when passing through an intersection without the right of way.
